Modulator LFO

The table below lists the properties of the Low-Frequency Oscillator (LFO) modulator. For more information on working with LFO modulators, refer to Working with LFOs.

Interface Element

Description

Name

The name of the modulator ShareSet.

Shared by

A list of objects that currently subscribe to the selected ShareSet.

Opens a search field where standard alphanumeric entries filter out unmatching elements from the view. Learn more in Using tables.

Click the Close icon to the left of the search icon to close the search field and remove the filter.

[Note]Note

The searches do not include elements in collapsed nodes of the List View, Query Editor, MIDI Keymap Editor, and Reference View.

Notes

Additional information about the ShareSet or the modulator settings that have been applied.

Interface Element

Description

Depth

The amplitude variation of the oscillator. Maximum amplitude is 1.0.

Default value: 100

Range: 0 to 100

Units: %

Frequency

The number of cycles per second.

Default value: 1

Range: 0 to 20000

Units: Hz

Waveform

The shape of the modulator, from among the following options:

  • Sine

  • Triangle

  • Square

  • Saw up

  • Saw down

  • Random: Selecting Random will randomly apply a level each time the modulator runs.

Default value: Sine

Smoothing

Low-pass filter over the waveform to smooth hard edges.

This parameter can reduce output gain depending on your configuration. For a square waveform with an LFO of 1 Hz, gain reduction can be observed with a smoothing value as low as 30%. The higher the LFO frequency, the lower the smoothing value for which gain reduction is observed (for example, 2 Hz = 25%, 4 Hz = 20%, 8 Hz = 10%). For triangular or sawtooth waveforms, gain reduction can be observed with a smoothing value as low as 10%.

Default value: 0

Range: 0 to 100

Units: %

PWM

The width of the pulse wave; only applies to the Square waveform.

Default value: 50

Range: 0 to 100

Units: %

Attack

The time it takes for the oscillator to reach full amplitude.

Default value: 0

Range: 0 to 100000

Units: s

Initial Phase Offset

The initial phase of the oscillator waveform.

Default value: 0

Range: -180 to 180

Units: °

Scope

Define how LFO instances are created:

  • Voice: An instance of LFO is created for every sound/object playback.

  • Note/Event: An instance of LFO is created for every playing instance, or note when used in MIDI context.

  • Game Object: An instance of LFO is created for each game object.

  • Global: A single LFO is created for the whole project.

Default value: Note or Event

[Note]Note

The RTPC cursors for LFO and Envelope modulators do not tell you their specific values at any point in time since they are determined by the modulator's internal properties.
